NTRODUCTION
CR87HT High Temperature Recorder
The CR87HT is a precision instrument used to monitor and record temperature
on a 6" circular chart. The CR87HT may be carried as a portable instrument or
mounted in a fixed location.
The CR87HT offers a variety of features to meet any temperature recording re-
quirements. A combination of three temperature ranges and four chart speeds
provide a high degree of flexibility. In addition, the chart rotation may be set for
single or continuous turn operation as required by a particular application. To
protect the data being recorded, the CR87HT uses an automatic battery backup
to maintain operation during a power outage.

ONTROLS
1.
The
3 DIGIT TEMPERATURE DISPLAY
provides precision temperature
reading of the environment monitored by the thermocouple sensor. When
the CR87HT is operating on battery power, the display will flash on once
every several seconds to indicate battery operation and to conserve battery
power. When the batteries are nearly discharged, the display will alternate
the display reading and "LO" to advise the operator that the batteries are
discharged and the CR87HT will shortly cease operation.
NOTE:
The battery backup feature of the CR87HT is primarily intended for
use in situations where primary power is lost for short periods of up to 48
hours. The CR87HT is not intended to be used as a battery powered instru-
ment. If the CR87HT is to be stored for an extended period, it is strongly ad-
vised to disconnect the battery pack and remove the batteries to avoid
damage to the instrument from battery leakage.
2. Th
TEMPERATURE RANGE SELECTOR
allows the user to choose the
desired temperature range for measurement and recording.
3. Th
CHART SPEED SELECTOR
allows the user to select recording time of
one full chart revolution. The corresponding chart has to be chosen ac-
cording to the desired chart speed and temperature scale. Chart part num-
bers are listed in this manual.
4.
PEN POSITION ADJUSTMENT KNOB
allows the user to adjust the position
of the chart pen to match that of the digital display. Usually, this adjustment
will be required after replacing the chart pen.
5.
CHART ADVANCE BUTTON
is used to set the chart to the correct time.
Press and hold the Chart Advance button until the desired time lines up with
the Time Pointer (Item 11).The chart is rotated counterclockwise only.
Movement of the Chart Spindle (Item 9) by hand can cause permanent
damage to the chart mechanism.
